Hey,
I am the co-founder of MTX-Platform. Basically we provide what you are looking for - a product that can provide the Technology for your Exchange, including the Hardware and Software. With our solution, you are free from creating a Technical team and investing money into Tech Infrastructure for the Exchange database.
Here is our link: mtxplatform.com
Currently, we have just rolled out the product, got some clients and really want to find more partners. So we introduce a promotion plan - You can try opening and running your Exchange for free cost of Technology to see if your business idea can work or not.
I think we should chat more for better understanding. Security is normally the main issue, we want to show you how we can assure you against fraud.
Contact me on Tele: @DuongBitsedo
Cheers, boss.
